About

T3 versus T4 as a primary treatment for palmer hyperhydrosis and effect on postoperative compensatory hyperhydrosis

Full description

Palmar hyperhidrosis (PH) is a benign sympathetic disorder that does not threaten health but affects daily activities, and may causes social withdrawal and even depression.1 An incidence of up to 1% has been reported by various series in the literature. The incidence in men and women is the same; however women are more likely to seek medical attention, which may explain the higher incidence of female patients in most surgical series [2,3]. Although various treatment options are available, including topical and systemic therapies, iontophoresis, regional nerve block, and botulinum toxin injection, each has its limitations 4. Video-assisted thoracoscopic sympathetic surgery is currently a worldwide accepted treatment of primary palmar hyperhidrosis (PH) 5. However, compensatory hyperhidrosis (CH) is the most common and serious side effect that occurs in 30-70% of patients after T2 or T2-3 sympathectomy 6. For that now T2 sympathetic surgeries are seldom used in PH. Procedures that involve T3 or/and T4 sympathetic ganglions are widely accepted in many centers with favourable results.5 But some patients still present with certain degrees of CH or over dry hands after operation 7, 8.

The aim of this study is to compare the two methods for the treatment of PH, in which the sympathetic chain was transected in merely one segment, on the level of either the third or the fourth ribbed, defined as T3 sympathicotomy or T4 sympathicotomy, respectively. Emphasis was placed on the evaluation of the efficacy, side effects, and patients' satisfaction rate to these two types of surgical therapy.

t3 sympathicotomy

Active Comparator group

Description:

The sympathetic chain was identified at the level of the crossing of the third or fourth costal heads after dissection of the parietal pleura and completely divided about 1 cm wide at the upper margin of the rib. With assistance of anaesthesia team we reinflate the lung totally in sequence with removal of the trocars. The same procedure was performed on the opposite side and ablation of the sympathetic chain overlying the rib was performed bilaterally. At the end of surgery, a postoperative chest x-ray was routinely taken to rule out pneumothorax or hemothorax.

Procedure: t3 sympathicotomy

Procedure: t4 symapthicotomy
